To all whom it may concern/.-

Be it known that l, ALIHQNSE Cori a citimen of the United States, residing at New York, in the county of New York and State of 5 New York, have invented certain new and coupled,

.useful Improvements in Detachable Pipe- Couplings; and'ldo herebydeclare the following to use full, clear, and exact description of'the invenlion, such as will enable others skilled in the art to which it appertains to makeand use the same, i

My invention relates, 'gcnerally, to that class of couplings which are used upon cars for conveying steam, hot air; and other heating'inedia from car to car, and particularly to the means for coupling the sections and to m eans fornllowing snflicient swing to preventt-he sections from breaking or becoming un- Thc object and nature of theinvention will more fullyappear from the subjoined description, and the novelty will be fully pointed out in'the claims, reference being had to the accompanying drawings, in which- Figure 1 represents an elevation of my device; Fig'. 2, a section, on an enlarged scale,of, .hne of the cylinders and its adjoining parts;

Fig. 3, a view showing one of the couplings in section and the other in elevation or bot tom plan; and .l ig. l, a detail showing the manner of securing the packing in place, on

a larger scale than that shown in Fig. 0.

A A represent the pipes extending from.

- the ball being turned in its socket when'that motion is necessary, and the nut is provided with an annular flange a for covering the packing. The hall end of the pipe is then ii'n'icrted'in a cylinder A, and the packing a. laid upon the end a of the cylinder, and the nut c screwed down'upon the screwthreaded end of. cylinder A The lower end of the cylinder is provided with a curved pipe A oi substantially the same shape as pipe A and provided with a ball a. at its end. It is socured in place by the same means as those shown at the upper end of the cylinder. 'io the free end of pipe A is secured a second pipe carrying one part of the coupling E.

in practice it has been found that the pressure of. steam in cylinder A is suiiicient to hold the ballsagainst their seat on packing a". I find, however, that it is desirable in some cases to have the balls held in contact with their seats, "This particularly so-when no steam is passing through the coupling, as the halls may then separate from their seats to a greater or less extent. To overcome this, a coiled spring a is inserted in the cylinder in such manner as to-havc its ends pressing inst the balls a. if desired, a second packin a, may be inserted between the ends of the spring and the halls A metal ring may be secured to the side of the packing to pro-- vent theanetal spring from wearing its face. These packings lit the bore of the cylinder, and are provided with the central aperture (L and the rounded seat a like packings These packings to prevent steam and also dirt from passing between the balls (1. and the cylinder. The dirt, if allowed to get hetweenthe parts just referred to, would soon wear away the, surfaces of the cylinder and hall and also the packing a To prevent the dirt from getting between. the packingd and the ball a. at the upper end of the cylinder, 1

provide a shield a which may he slipped over the end of pipe Ah My preferred. shield,- however, is made of lead, which is split at a, so that it can he slipped around the pipe and the cd 'cs of the slit brought together. By

such a construction the shield can be made.
